Reaction on Climate Change The Philippines has been considered as a highly vulnerable to current (natural disasters)‚ as well as future climate-related risks due to its geographical location and physical characteristics. It lies along the Western Pacific Basin (a generator of climatic conditions such as monsoons‚ thunderstorms‚ Inter-Tropical Convergence Zone‚ typhoons‚ among others) making it a path of an average of 20 tropical cyclones annually‚ nine of which makes a landfall.

Chemical Reactions & Equations CHEMICAL REACTION : In a reaction when the original state of the particle changes and it cannot be reversed by simple physical means‚ this type of reaction is known as chemical reaction. Example :- Fermentation of grapes‚ burning of wood etc. In this reaction we have seen that after burning of wood‚ coal is formed and we cannot make wood from coal. PHYSICAL REACTION : In a reaction when original state of the particle can be recovered by any means then this type of

9/25/13 Endothermic Reaction Lab Report The Effect Ammonium Nitrate has on the Temperature of Water During this lab students are going to mix water and ammonium nitrate one gram at a time and observe the change in temperature that is occurring. The students are then going to record the data on a table and later will be able to make a graph of the results. A hypothesis for this lab could be if ammonium nitrate is added to water then the water temperature will decrease. . Hypothesis: If
